Poll: What can I do to make more male friends?

It seems like a kind of petty and obvious question, but I can't really pinpoint what I'm doing wrong. I've got plenty of friends, so it's not that I'm socially inept or anything. It's just, out of all my friends, only about three of them are guys. I don't act feminine. I'm into masculine things. I like to watch and talk about sports, cars, and girls, and those three things are at the top of my list of interests, but still, guys just don't seem to like me. I like my friends, but sometimes I just need to hang out with other guys. I can't put up with girls all of the time.
